Crystals Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributors before integration. Confirm that the 2-SMD package dimensions align with your PCB footprint requirements. Ensure that the 12.5 pF load capacitance matches your circuit design specifications to maintain the stated ±20 ppm frequency tolerance. Check for any recent product lifecycle notifications regarding availability or obsolescence.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for time-based operations in space-constrained designs. The 12.5 pF load capacitance is standard for many microcontroller interfaces, simplifying circuit design. Consider the ±20 ppm tolerance if higher precision is not critical. The wide operating temperature range makes it suitable for diverse environmental conditions. Evaluate the ESR value against your oscillator circuit's drive level limitations.
